Directions

Make lime butter: Purée garlic with lime juice, salt, and pepper in a blender until smooth. With motor running, add melted butter and blend until emulsified, about 30 seconds.

Make salmon: Prepare grill for cooking over medium-hot charcoal (moderate heat for gas).

Season salmon all over with salt and pepper, then grill, flesh sides down, on lightly oiled grill rack (covered only if using gas grill) 4 minutes. Turn fillets over and grill (covered only if using gas grill) until just cooked through, 4 to 6 minutes more. Sprinkle fillets with zest and top each with 1 tablespoon lime butter sauce.
